Firefox rocks!
If Firefox doesn't work, I would try changing your DNS servers to a publicly-accessible set.
1. Start -> Control Panel
2. Choose "Switch to Classic View" on the left
3. Double-click "Network Connections"
4. Right-click your ethernet adapter (usually Local Area Connection something) and choose Properties
5. In the list under "This connection uses the following items:", click on "Internet Protocol (TCP/IP)" and click the button labeled Properties.
6. At the bottom of the panel that appears, click "Use the following DNS server addresses:" and fill out the boxes so that they read:
Preferred DNS server: [ 4 ].[ 2 ].[ 2 ].[ 1 ]
Alternate DNS server: [ 4 ].[ 2 ].[ 2 ].[ 2 ]
Click OK, then OK out of all the other dialogs you brought up. Restart your computer and try looking at one of the websites in question.
You can reverse the process by returning the option in step 6 to "Obtain DNS server address automatically".
